Although the guys all lament the fact that there is no fighting in the version of video hockey they are playing, that version is NHLPA '93, which did, in fact, have fighting (as well as being able to make someone's head bleed). Fighting was not removed from the series until NHL '94.
In the trailer Trent says the part he was auditioning for was called "Brother". Then he says the casting director said "Trent when you walked in the room, I didn't see Trent Walker come in here, I saw Big Brother come in here." Then he says the director said "I think you're a little old for the part of Brother."
When Sue leaves Trent to finish up the pep talk with Mike at the Dresden, as Mike walks away, Rob is seen sitting in the background, in a chair at a different table. When we cut back to the guys at the table, Rob is back where he was originally sitting, as if he never moved.
When Mike buzzes Rob up to his apartment, he picks up the phone handset from the floor next to him. But only a minute earlier the handset was on the phone base unit on the desk, and there is nothing to show how the handset got from the desk to the floor.
When they stop leaving Vegas on the highway and Trent is relieving himself, his car is red. Later when they all leave to head out to the party, his car is navy blue/black. However, the later scenes are shot at night with only street lights for illumination. That affects the way the car looks.
When Trent looks at the "lower stakes tables" his head is already looking in the other tables direction and then he's seen turning his head again. Throughout the seen there are other more subtle head position flaws.
In the girls' trailer, several cuts showing Mike and the Judy Garland impersonator holding hands are not fluent. The most noticeable is when "Judy Garland" takes a drink with her left hand and then suddenly back in Mike's hand left hand.
At the blackjack table, the position of Mike's hand (5 of hearts 6 of hearts) keeps changing from higher up on the table to lower on the table and then back higher again between shots. You can notice this by the position of the lettering on the table felt relative to where the cards lay.
When Mike changes his $300 for chips the dealer starts placing the money down with his left hand with the pile of twenties and cards in his right hand. When the scene cuts, the dealer is then placing the bills down with his right hand.
In the diner after the club scene where Mike and Michelle dance together, Trent can be seen holding a jar of syrup in his left hand and silverware in his right hand as the waitress brings the food. In a subsequent shot, Trent is holding the syrup in his right hand. However, a cut back to the original shot reveals Trent again holding the syrup in his left hand and the silverware in his right hand.
During the Rob/Mike apartment scene, in an over the shoulder shot (after he talks about the pain hurting less each day) Rob brings his hand up to his chin, but then in the next shot, his hands are on his lap.
In the last of the scenes in Mike's apartment, when the camera zooms in on him while standing in the kitchen and talking on the phone, a portion of a light stand can be seen behind him in the final moments of the zoom.
When Mike and Trent pull up to the hotel in Las Vegas, you can see that they are pulling up to the Stardust Resort & Casino, which is located on The Strip. However, once they're inside the casino you can see that the blackjack tables bear the name of the Fremont Hotel and Casino, which is based on Downtown Las Vegas.
When Mike buys $300 in chips at the casino, the dealer counts the bills and hands him three black $100 chips. They are identical to standard poker tournament chips used in most casinos around the country and clearly say "No Cash Value" on them.
